Error with arduino Mega while connecting with RFID RC522

Hay ! am working on a project ,in which i have to use RFID and Arduino mega but when i tried it with the help of examples (library)..it's responding nothing ..i have done all connections right ...please help me...here is CODE:

/*

  • MFRC522 - Library to use ARDUINO RFID MODULE KIT 13.56 MHZ WITH TAGS SPI W AND R BY COOQROBOT.
  • The library file MFRC522.h has a wealth of useful info. Please read it.
  • The functions are documented in MFRC522.cpp.
  • Based on code Dr.Leong ( WWW.B2CQSHOP.COM )
  • Created by Miguel Balboa (circuitito.com), Jan, 2012.
  • Rewritten by Søren Thing Andersen (access.thing.dk), fall of 2013 (Translation to English, refactored, comments, anti collision, cascade levels.)
  • Released into the public domain.
  • Sample program showing how to read data from a PICC using a MFRC522 reader on the Arduino SPI interface.
    *----------------------------------------------------------------------------- empty_skull
  • Aggiunti pin per arduino Mega
  • add pin configuration for arduino mega
  • http://mac86project.altervista.org/
    ----------------------------------------------------------------------------- Nicola Coppola
  • Pin layout should be as follows:
  • Signal Pin Pin Pin
  • Arduino Uno Arduino Mega MFRC522 board
  • Reset 9 5 RST
  • SPI SS 10 53 SDA
  • SPI MOSI 11 51 MOSI
  • SPI MISO 12 50 MISO
  • SPI SCK 13 52 SCK
  • The reader can be found on eBay for around 5 dollars. Search for "mf-rc522" on ebay.com.

#include <SPI.h>
#include <MFRC522.h>

#define SS_PIN 53
#define RST_PIN 5
MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.

void setup() {
Serial.begin(9600); // Initialize serial communications with the PC
SPI.begin(); // Init SPI bus
mfrc522.PCD_Init(); // Init MFRC522 card
Serial.println("Scan PICC to see UID and type...");
}

void loop() {
// Look for new cards
if ( ! mfrc522.PICC_IsNewCardPresent()) {
return;
}

// Select one of the cards
if ( ! mfrc522.PICC_ReadCardSerial()) {
return;
}

// Dump debug info about the card. PICC_HaltA() is automatically called.
mfrc522.PICC_DumpToSerial(&(mfrc522.uid));
}

i have done all connections right

Obviously not.

Perhaps instead of claiming this, you should instead post a schematic AND a picture that shows the actual wiring.
